If a shareholder holds fractional shares of a security as of the security’s record date, the shareholder is eligible to vote their proxy ahead of the upcoming meeting and their experience is identical to that of full share position holders.
The fractional position voted is added to the aggregate vote total for the security before sending the aggregate vote record to the company’s tabulator. Each tabulator may follow differing policies for counting fractional share positions, and therefore it is possible that a tabulator may follow certain rounding practices or discard fractional amounts in certain circumstances.
Everyone regardless of how many shares they have (fractional or otherwise) is getting their right to vote. All votes are collectively pooled before being communicated to the company
